Figure : Isolated system illustrated before and after. The heat capacity of 1 kilogram of Pb is given by CPb ; the heat capacity of 1 kilogram of water is given by CH2O; all other heat capacities in the isolated system can be neglected. CPb and CH2O may be considered independent of any constraints (e.g., constant pressure or constant volume) and to be independent of temperature. i Derive an expression for the final temperature after a process leading to the figure on the right of the illustration. ii Would the temperature be larger or smaller if the block of lead had fallen to the left (i.e., into the water)?
